Question

The cost of the book is 5 rupees more than twice the cost of a pen. Show

this using linear equation by taking Cost of book(x) and cost of a pen(y).​

Answer 1

Given :-

The cost of the book is 5 rupees more than twice the cost of a pen.

To show :-

We have to represent the given question in the form of linear equation

Step - by - Step - Explanation :-

Let the cost of the book be x

Let the cost of the pen be y

According to the question,

The cost of the book is 5 more than twice the cost of book

That is,

x - 2y = 5

Hence, The required linear equation is x - 2y = 5
